Dear OpenMPI Developer, i have a doubt regards mpi_leave_pinned parameter. Suppose i have a simple for:
for( int i=0; i< 100; i++) MPI_Reduce(a, b, .......) My question is: if i set mpi_leave_pinned= 1, buffer memories are pinned in the entire process, or just into the for cycle? When the cycle is finished, a and b memories, are unregistrered? Thanks in advance. -- Ing.
